Snoring and Sleep Apnoea — When Snoring Is a Medical Problem
Also described as loud snoring, sleep apnoea, gasping in sleep.
Snoring becomes a medical concern when a partner notices pauses in breathing, or when you wake unrefreshed and feel sleepy during the day. That pattern suggests obstructive sleep apnoea, which raises blood pressure and cardiac risk and is confirmed by a sleep study.
🚨 Get emergency care if you have
- •Witnessed pauses in breathing during sleep
- •Waking gasping or choking
- •Falling asleep while driving or in conversation
- •Morning headaches with high blood pressure
- •Snoring in a child with restless sleep or mouth breathing
What causes snoring?
Obstructive sleep apnoea
Repeated airway collapse during sleep, causing pauses, oxygen dips and daytime sleepiness.
Excess weight
The commonest reversible contributor. Weight loss measurably reduces apnoea severity.
Nasal obstruction
A deviated septum, allergy or polyps forcing mouth breathing.
Enlarged tonsils or adenoids
The usual cause in children, and a treatable one.
Alcohol and sedatives
Both relax the airway muscles and worsen snoring and apnoea.
How it is investigated
- ✓Sleep study (polysomnography), at home or in hospital
- ✓Epworth sleepiness score
- ✓ENT examination of the nose and throat
- ✓Blood pressure, thyroid function and blood sugar
Not every patient needs every test. The consultation decides which of these apply to you.
Frequently asked questions
Is snoring always sleep apnoea?▼
No. Plenty of people snore without apnoea. The difference is whether breathing actually stops: witnessed pauses, gasping arousals, unrefreshing sleep and daytime sleepiness point to apnoea, and a sleep study settles it objectively rather than by impression.
Why does sleep apnoea matter if I feel fine?▼
Untreated apnoea is linked to high blood pressure that resists medication, atrial fibrillation, stroke and diabetes, and it raises the risk of road accidents. Treating it often improves blood pressure control as well as daytime alertness.
